Highlights of Topping QLS QA890 DAC

  • High standard power supply design
    - 2 toroidal transformer for digital and analog circuits separately with vibration isolation and absorbing design, and without interfering with the digital clock circuit completely.
    - TPS7A4700,LT3042,LM1086,LT1965,ADP151....More than 20 independent ultra-low noise LDO for each circuit module offer the power supply, to ensure the cleanest sound.
  • Provides 6 kinds of sound mode can be options (5 filters mode + ALL To DSD) to suit different sound style preferences.
  • Pre-amplifier inside with on/off and volume control (volume set to 100 will auto off the pre-amplifier).
  • Two different sound style's coaxial input port, while coaxial 1 with impedance automatic matching function.
  • 2 groups AK4495S independent for left and right channels, left and right separation, digital and analogy separation, excellent sound separation.
  • Using the unit price of more than USD 20 Switzerland Schurter DD12.9121.111 Power Entry Connector Receptacle, ensure that it is in any electrical environment are sound performance.
  • Using CMC805 Silver-plated high-end input RCA coaxial socket, balanced output using Neutrik connector.
  • 4-layers PCB for all circuit boards.
  • The QA890 DAC designed use double AK4495S, and It can set the built-in filter parameter, it can auto-detect the input signal DSD or PCM.
  • There are no design compromises, built with all high-grade audio parts, complicated power supply systems, and clock circuits.

The following items are included with your Order

  1. QA890 DAC x 1
  2. Power Cable x 1
  3. User Guide x 1
  4. Remote Control x 1 [Option]
  5. USB Cable x 1 [Option, Only for With USB]

Bundle 1  :DAC + Remote control
Bundle 2  :DAC+  USB Cable + Remote control

A

24Bit / 192KHz PCM and DSD Support

  • QA890 Supports up to 24Bit / 192KHz and DSD64 / 1Bit / Stereo (DoP input or USB).

ALL To DSD mode, hear more than CD

  • Provides 6 kinds of sound mode, include five different sound filtering modes, the more innovative provides ALL To DSD mode, to meet a variety of listening style needs.
  • ALL to DSD mode, DSD decoding due to the short path, the decoding process is simple, full DSD decoder, no need to find for DSD music file.
  • ALL to DSD mode. All formats can be converted to SACD 1Bit 5.6MHz high resolution, even if the original signal is PCM, after this conversion, it is more like a very fun with the fun taste DSD sound playback to listen to a CD.

B

Redesign the high-quality clock.

  • Do not use traditional TCXO clocks. We had listened and compared varieties of TCXO clock found that there was almost a problem, the sound is too modern and the lack of traditional music aesthetic beauty.
  • QA890 redesign the low noise power supply with low noise and low jitter clock, Ensure a vivid natural sound detail and precise stereo sound field while also having good musical aesthetics.

Isolation + filter to eliminate noise and EMI

  • The newly developed full digital signal/ground isolation system eliminates the impact of noise from the digital audio processing section and the MCU control section on the DAC.
  • Multiple digital signal channels to increase the custom filter device to prevent high-frequency noise caused by the deterioration of sound quality, to achieve a clear, smooth playback sound quality.
  • The isolated I2S signal will then be perfect for waveform reproduction and clock phase correction, making the music dynamic range wider, playback more accurate, especially in the small dynamic ups and downs and transparency is even better.
  • Each part of the circuit independently, each circuit board design with a noise absorption circuit.
  • The AC earth has the corresponding device to absorb noise, eliminating the interference of various parts of the noise and noise, improve the signal to noise ratio, so that the music background quieter, improve the overall analysis.

QA890(With USB) Also have an XMOS USB Bridge to Computer (Option)

  • The QA890(With USB) also has an asynchronous High-Speed USB to a digital audio interface that extracts the highest possible audio quality from computer audio sources.
  • The QA890(With USB) has High-Speed USB 2.0 input data connection  Sampling rates up to 192 kHz and word lengths up to 24 bit are supported.
  • Great care was taken in the design of the QA890(With USB) to isolate the noisy computer / USB environment from the digital audio output. The USB receiver and processing are powered by the computer, while the output line drivers are powered by a separate isolated linear power supply.
  • The QA890(With USB) USB is designed to work with both Apple Macintosh and Windows PC computers. Microsoft Windows PC's require the included Windows driver which works with Windows XP, Vista and 7 and Windows 8 / 10
